To all wiom it mayconcern:

Be it known that I, WILLIAM H. Hoornn, a citizen of the United States, residing at Lynn, county of Essex, and State of Massachusetts, have invented an .improvement in Channel-Lip-lurning Machines, of which the following description, in connection with the accompanying drawings, is a specification, like characters on the drawings repre- I senting like parts.

The invention to be hereinafter described relates to lip turning machine and has for its object to provide a device of this character which will `be simple in construction, ef-

cient in'operation, and whereinthe parts l shall be so related and disposed that the l work may be readily putin operative position with respect to the parts that act upon it, and be properly guided throu `hout the extent of the lip turning action.l hese with other objects and purposes of the invention will be readily understood by those skilled in the art from the following description of one form .of the invention selected for illustrative purposes.

In the drawings:-Figure l is a side elevation of lip turning machine embodying the features of the present invention, sulicient only of the frame and other parts being illustrated to show the relation end connection of the invention therewith. Fig. 2 1s a detached detail viewy of a portion of the machine head looking in the direction 0f the arrow Fig. l. Fig. 3 is a detached detail view showing the lost. motion connection l between the treadle operated rods for depressing and swingingthe feed wheel andv tool carrier respectively.-

The frame A 'may be of any usual or desired construction suitable to support the operative parts in desired position, said frame preferably rising from the floor, as usual.

Mounted in a suitable bearing l carried by the frame A is the shaft 2, shown by dot ted lines Fig. l, said shaft having mounted thereon the worm gear 3 preferably running in an oil cup e, and driven from a worm 5, mounted on the cross or worm shaft 6, carried by brackets, projecting from the l frame A.

Mounted in a vertically movable hearing 9, is a shaft 8 carrying the feed wheel B, said shaft 8 being operatively joined to the shaft 2 by the well known Oldham coupling wings or 10, so that while shafts 2 and 8 are connected for rotation in unison, the sliding bearing 9 and shaft 8, together with the feed wheel B, may be raised or lowered, as will be read- -ily understood by those skilled in the art. It will likewise be the Qldham coupling, the shafts 2 and 8 may be otherwise operatively connected, so that the feed wheel B may be raised or lowered.

Projecting from the frame A arm or bracket ll, upon which rests one end of a coiled spring l2', the other end whereof bears upon and normally maintains the bearing 9 and its connected parts in raised or working position, a `stop 13 being eniployed to limit the upward movement of said parts. Connected to the movable 'or sliding bearing 9 is a treadle rod 14 which extends downward to. a treadle or other operating device not necessary to illustrate because old and well known in the art.

Rotatably mounted in the bearings C and D secured to or forming part of the main frame A is the vertical outer tool shaftl to which is lixed the operating pulley 16, driven by the belt 17, which extends over similar pulleys 18 on the worin shaft 6, and is driven from any suitable source of power. From this construction it will be clear to oneskilled in the artthat the belt 17 serves to rotate the worm shaft 6, `the connected feed wheel B, and the tool shaft l in a convcnient and eliicient manner. To the lower end of the tool shaft is connected the lip turning tool for acting upon the outer lip, adjacent the sole edge, and which in 'the present forni of the invention comprises projections 19, the action of which in conjunction with the opposed lip turning tool and associated guides will hereinafter more fully appear.

To extensions 20 of the bracket D' which supports the bearing D of the tool shaft l5, is pivotally connected at 22 a small frame 2l, which, for identification, may be termed the inner lip frame. This pivoted frame 21 has .rotatably mounted therein the vertical shaft 23, the lower end of which carries the inner lip turning means, preferably. though not necessarily formed by vertical grooves or corrugations 24- in the lower end of the inner lip turning shaft 23.

The inner lip turning frame is disposed so as to swing on its pivotal axis 22, betweenv obvious that instead of` is a guide l the side or cheek extensions 25, 25 of the bracket D", 'said side or cheek extensions thus serving as guides for thel frame 21 as it swings on its axis and as steadying means for the frame during the action of the inner lip turning tool, as will be clearly under stood by't-hosev killed in the art. To the,`

upper portion of the inner lip turning frame 21 is connected an arm 26, preferably .secured thereto by screws or other suitable means 27, 27, and to the free end of said arm is appropriately jointed the operating rod 28, normally maintained in raised position (Fig. 1) by means of a spring 29 surrounding the rod and bearing at its ends respectively upon the frame at 30` and the shoulders 31 on the rod. The. operating ro'd 28 extends downward below the machine `head and passes through 4the end 33 of an adjustable-sleeve-32 secured vto the treadle rod 14 (Figs. 1 and'3), the lower portion of the operating rod having attached thereto a collar 34 some distance below the slve 32. From this construction it'will be clear to one skilled in the art, that upon degression ofthe treadle rod 14, the feed wheel will be rst moved downward to enable the work to be carriedbelow the lip turning tools, and thereafter, by engagementv of the working relation with the sole and lips thereon, and its second eiiec't will be to per-` mit the feed wheel B to close upon and clamp the work against the guides to be' now explained.

Projecting upward from the main frame ,A is a short guide supporting standard35` recessed to accommodate an outerchannel guide 36 adjustably mounted thereon, said outer channel guide 36 being provided with a curved. advance edg 37 and a bottom portion 38 extending beneath the lower end of the. outer lip turnin tool, said bottom portion 38 affording a' caring .surface extending into theouter channel of thev sole S, as in icated in Fig. 1, and supporting the upward thrust of the work due to the upward tendency'of the feed Wheel B, as will be readily understood, while its curved edge gives the initial raise .to the outer lip that 1t may be fproperly treated by the outer lip turning tool.

The feed of the work is in the direction of the arrow, Fig. 2, so that the curved forward lip raising edge of the guide 36 rst actson the work, then the outer lip turning tool turns the lip to the up position shown, while the bottom surface of the guide travels in the outer channel. Disposed on the side of the outer lip turning tool opposite the edge 37, is a lippresser 39 (Fig. 2) having a lower portion-to extend into the channel and an upper portion to bear against the upturned lip and press or hold ing the tool 24 to working position, asA

already explained," the inner channel guide, also, is placed inthe channel and beneath the tool to thereby act not only as a guide but 'as a support forthe sole against the upward thrust of the Afeed wheel, similar to corresponding functions ofthe outer guide 36. Likewise by projecting beneath the yends of the 'inner and outer lip turning,

tools, the 4`inner vand outer guides protect the 'work froml being distorted or its line of feed disturbed by the ends ofl thetools turning against the surface of thechannels.

It has already been stated that the' inner lip turning shaft .23 is mounted in the frame 21, and todrive said shaft in` unison with the outer lip turning 4shaft .15, the latter is provided with a pinion 44 which operatively engagesl a pinion 45 secured to the inner lip turning shaft'23, suiicienty play .ori .lost motion being provided to allow the shaft 23 to swing with the frame 21, as. will be readily understood. Such play or lost motion .is negligible in the practicaloperation ofthe machine, because the pinions are located near the pivotal point of the frame 21.

To limit theswing of the tools toward each other, the swinging framey 21 is provided with an adjusting screw 46.

- The operation of the machine will be readily understood from the construction described,it being apparent that variations in form, location and lcharacter of parts may be made within the limits of mechanical skill Without departing from the spirit of the present invention, which contemplates` the simultaneous treatment and raising of two channel lips by rotating tools worklng upon the lips between them and guides for the work disposed to engage the .channel of'its adjacent tool. It willalso be clearthat in .placing a piece of work in position between` `the tools that a simple depression of the treadle servesto lower the work support or feedI wheel, and then separate not only the tools by the movement of the swinging france but also the tivo channel guides.
